The orientation of the screen relative to the element under study is provided by the mechanism 2 for moving and fixing the screen.
В соответствии с теорией муарового метода на негативе образуютс муаровые полосы, их осевыми лини ми вл ютс линии, вдоль которых частные производные нормального к поверхности перемещени по произвольному радиусу относительно центра кон-центрических окружностей растра посто нны.In accordance with the theory of the moire method on the negative, the moire bands are formed, their axial lines are the lines along which the partial derivatives of the normal to the surface displacement along an arbitrary radius relative to the center of the concentric circles of the raster are constant.
Обработку полученных картин производ т в соответствии с общей теорией муарового метода отраженных картин, но направление исследовани характеристик напр женно-деформированного состо ни выбирают произвольным и совпадающим с радиусами концентрических окружностей растра.The processing of the obtained pictures is carried out in accordance with the general theory of the moire method of reflected pictures, but the direction of studying the characteristics of the stress-strain state is chosen arbitrary and coinciding with the radii of concentric circles of the raster.
Дл оболочек вращени муаровые картины, полученные предлагаемым методом характеризуют углы поворота нормалей к срединной поверхности оболочек. Обрабатывают такие картины в соответствии с общим методом обработки отраженных муаровых картин при исследовании пластин. Получают характеристики напр женно-деформированного состо ни оболочек ло геометрическим и физиче4For shells of rotation, the moiré patterns obtained by the proposed method characterize the angles of rotation of the normals to the middle surface of the shells. Treat such paintings in accordance with the general method of processing the reflected moire patterns in the study plates. The characteristics of the stress-strain state of the shells are geometrical and physical.
